PRINTING-PRESS APPLIANCE.

7 Specification of Letters Patent.

Patented Apr. 17, 1919.

' To all whom it may concern:

Be it known that I, JAMES E. DOYLE, citizen of the United States, residing at Cleveland, in the county of Guyahoga, State of Ohio, have invented a new and useful Improvement in Printing-Press Appliances, of which the following is a specification, the principle of the invention being herein explained and the best mode in which I have contemplated applying the principle, so as to distinguish it from other inventions.

This inventive conception relates to an appliance adapted for the Gordon type of press involving a platen and inking surface having angular relation to each other and which are successively traversed by a reciprocal saddle carrying inking rolls. This particular appliance incidentally embodies certain of the supporting parts shown described and claimed in my copending application of like title, filed October 29, 1913, Serial Number 797 ,941.

The primary object of the appliance herein described is to make possible the ready as well as efficacious conversion of the type of press mentioned, so that distinct multicolor impressions may be produced and yet have the uniform distribution of the difl'erent colored inks accomplished the while through the agency of a vibrator without permitting them to become inter-smeared. A secondary object is the designing of various details such that they will cooperate to the end of satisfactorily attaining the results sought.

The inventive conception of means is hereinafter explained and variously combined in the claims. While the annexed drawing and particular description thereof together set forth in detail several certain means constituting my invention, the means disclosed however, are but some of various mechanical forms in which the principle of my invention may be applied.

Referring to the drawings in which like characters of reference designate equivalent parts throughout:

Figure I is a side elevation of the upper swinging portion of a press embodying one form of my invention.

Fig. 11 is a rear elevation of the same.

Fig. III is an elevation of one detail.

Fig. TV is a vertical section taken on the center line of the saddle, certain parts being seen in elevation.

Fig. V is a plan of a modification in re-' speet to an equivalent detail.

Fig. V1 is a section on line VI VI of Fig. V.

This appliance is mounted in part rigid connection with, and in part so as to be movable upon the appliance of my copending application earlier referred to. Accordingly so much of the drawings, especially Fig. I, as represent parts of the press which are identical with those shown in the preceding application will be designated throughout with similar characters of ref erence.

The frame 1 is formed on opposite sides near its upper extremity with two pairs of pads designated respectively as 2 and 3. The upper extremity l of the track-forming edge and the seat formed by the two angularly related surfaces 5 and 6 are well seen in Fig. I. A carrier 7 pivotally mounted to the frame at 8 is adapted to coact with the swinging movement of the frame. Two actuating rods 9 articulate in an operative manner with this carrier 7. The manner in which the rods 9 are connected to the saddle 7 has not been indicated since it forms no part of this invention and is furthermore well known to the art. The free extremities of the rods 9 are pivotally connected to saddles 10 which include each a pair of inking rolls 11. A support 12 hav ing angular outward extensions 13 is provided to extend across the frame. These extensions are adapted to rest upon the two oppositely disposed pads 2 and become secured thereto as will hereinafter appear. The interjacent portion of the support 12 is of inverted U shape and its middle portion 14L- is provided with a boss 15 having a bore 16. It is upon this boss that the conventional inking disk may be mounted if desired, and as will be explained in connection with the modification illustrated in Figs. V and VT. The upper annular surface of the boss 15 is formed with four equispaced cams 17. The interjacent portion la is furthermore formed with an arched arm 18 having a curved slot 19 which should be an arc of a circle. The inking disk 20 here employed is provided underneath and centrally with a boss 21 which is likewise of circular crosssection and of corresponding dimension as the'boss 15. The under surface of theboss 21 is similarly fashioned with four equi-' spaced cams 22 adapted to rest upon and cooperate with the cams 17 whereby, as will be readily understood, a rotation of the disk 20 contrives to elevate or depress the same with respect to the support 12. Athumb screw 23 extends through the opening 19 and into a suitable screw threaded opening in the under surface of the disk 20. Through the agency of this screw, which when loosened may be slid along the slot 19, the inking disk may be raised or lowered at will and furthermore fixed in various positions relative to the support 12 and incidentally to that plane of travel of the rollers 11 which is prescribed at the uppermost point of the edges 4. 'A pair of my type of brackets 24 having diverg ing portions 25 adapted to lieupon the extremities 13 respectively, are employed. The upper extremities 26 of the two brackets 24 are inclined rearwardly and slotted as seen in Fig. I. An inking fountain rests upon such upper extremlties of the brackets 26 and 1s held in position by means of cap screws 27 extending through the slots just mentioned. It will be noted from the inspection of Fig. II that the fountain employed in connection with my invention is provided with a number of partitions P whose purpose will later become apparent. The forward upper edges of the brackets 24 are formed as angular extensions having surfaces 29 and 30 which lie contiguous with the surfaces 5 and 6 respectively. The upper edges proper 31 are straight track-forming continuations of the track-forming edges 4.

The upper surfaces of opposite ends of the portion 14 are formed as inclined pads 33. A bar 34 provided underneath with a pair of bosses having under surfaces 35 complementary to the upper surfaces of the pads 33 overlies the same and is secured to the support 12 through the medium of a pair of cap screws 36 one of which is seen in Fig. I. This bar is also formed with an upwardly projectin extension 37 having a smooth upper surface 38 substantially paral lel with the edge 31. Another bar 39 with angular downwardly projecting bosses 40 at opposite ends, is disposed between and secured to the lower forward portions of the brackets 24 by cap screws 41. The upper surface 42 of the bar 39 is similarly inclined so as to bein line with the upper surface 38. The forward edge 43 of the bar 39 is purposely slightly inclined in a rearward direction as seen in Fig. I.

A plurality of inking plates 44 are intended to restupon thesurfaces 38 and 42;

These plates may be of varying width as exemplified in Fig. II and may be furthermore spaced given distances with respect to each other. They aresecured to the bars 34 and 39 as will now be described. The inking plates 44 are provided at one end and underneath with projections 45 having rear surfaces 46 similarly inclined as the forward edge surface 43. The other ends of the inking plates 44 are also provided underneath with projections 47 through which adjusting screws 48 extend. The length of the plates should be such that the projections 45 and 47 will inclose the front and rear edges of the bars 39 and 34 respectively. The thickness of the plates 44 should be such that their upper surfaces will lie approximately flush with the upper edges 31 in order to allow of their being traversed by the inking rolls 11. have been disposed so asto inclose the two bars they are clamped in place thereon by means of the screws 48. These latter by engaging the beveled rear edge of the bar 34 draw the surfaces 46 into contact with the surface 43 and thereby lock the several plates against displacement.

The conjunctive feature of my invention is illustrated in F IV of which only so much will be described as is necessary for the purpose in hand. In this figure is shown a portion of the saddle construction including the rollers .49 of the inking'rolls which rollers are adapted to travel upon the edges 31. At one end of the saddle is anidler gear 50 adapted to mesh with the rack located alongside the edges 4 and 31. Above and in mesh with theidler 50 is a driving pinion 52 and this is mounted upon a spline shaft which partly supports so as to be removable a vibrator surface '54 having formed on its peripherya plurality of annular grooves 55. The vibrator 54 is hollow and formed on its interior with the After the projections 45 and 47' readily insure of correspondence with the number and width of the inking plates 44. During operation the spacing of the plates 44 should be adjusted with .respect'tothe axial throw of the vibrator 54 in order to make certain'that any side of a groove intersects the vertical plane of but one edge of any particular plate. In this manner the intersmearing of the chiferent colored inks which are stored between dlfferent'pairs of adjacent partitions in the-fountain to be deposited therefrom upon the corresponding plates, is positively precluded.

The modification to which Figs. V and VI relate resides in removably attaching a plurality of inking plates 59 directly upon the conventional type of inking disk long in use. In accordance with this motion the fastening agency consists for eachiplate of a pair of clamps 60 having similarly bent edges 61 and 62. The part 61 is adapted to engage the under surface of the disk 20, While the somewhat longer part 62 is adapted to engage the under surface of the proximate overhanging portion of the plate 59. Thumb-screws 63 pass through the clamp 60 to engage suitably screw-threaded openings in the under surface of the plates 59 whereby a tightening of the thumb screws 63 tends to hold the disk 20 and plates 59 rigidly with respect to each other and in the several locations laterally of each other that may have been determined upon. Meanwhile the adjustable mounting of the disk 20, which constituted one of the features of the invention disclosed in my pending application identified at the beginning of this specification, is brought into advantageous use here. It will be noticed that the disk has been depressed to such an extent that the upper surfaces of the plates 59, are brought into the same inclined plane as that which the disk would properly occupy for single color work.

My invention being described with sufficient thoroughness, what I desire to secure by Letters Patent and therefore claim spe cifically, is:

1. A printing press appliance comprising in combination, a frame, a track, an inking disk carried between said tracks, a saddle, rollers upon said saddle and movable along said track, an inking roll mounted upon said saddle and adapted to travel over said disk, a plurality of inking plates superimposed upon said disk, means for fixing the said plates to said disk, and means for independently adjusting the elevation of said disk whereby to regulate the pressure between said inking roll and plates.

2. A printing press appliance comprising in combination, an inking roll, means for actuating the same, an inking disk beneath the path of travel thereof, a plurality of inking plates detachably supported by said disk and overlying the same, said plates being spaced with respect to each other, and means for adjusting said member in a direction perpendicular to the plane of said plates whereby to effect a contact of given pressure between said roll and plates.

3. A printing press appliance comprising in combination, an inking device, a plurality of elongated inking plates of equal thickness arranged in a row thereacross, an inking roll yieldingly held against said plates, means for fixing said plates in various positions with respect to each other, and distinct means for adjusting said surfaces whereby to control the pressure of said roll upon said plates.

4:. A printing press appliance comprising in combination, an inking disk, a plurality of inking plates detachably alined upon such disk, roller tracks therealong, a pair of inking rollers movable upon said tracks so as to frictionally engage said plates, a vibrator disposed therebetween and provided intermediately of its ends with an annular groove, said vibrator having frictional lineal contact on opposite sides of said groove with said inking rollers, means for actuating said rollers and vibrator together, means for sliding said vibrator in the direction of its own axis, and means for effect ing a relative adjustment of said disk and rollers for the useful purpose specified.
